POST /v1/uploads (Task 18, A03): @@unique(userId, clientTaskId) idempotency
anchor — same params return the original session (201, no duplicate photo);
param drift (album/bytes/contentType/extension) -> 409 UPLOAD_SESSION_CONFLICT.
photos.objectKey is set to the FINAL originals key at init while the session
holds the staging key; IDs come from an app-side cuid-like generator so both
self-referencing keys are written in one transaction. Credential is a real
MinIO presigned PUT (SIGNED_URL_TTL_SECONDS, lazily read). Permission order:
album invisible 404 -> member 403 -> uploadEnabled 409 -> size/ext 400 ->
category ownership 400. No audit on init (audit anchors on complete).
Pre-step for Task 19: QUEUE_PHOTO_PROCESS contract constant + lazy-safe
BullMQ queue producer (Redis down at boot must not crash the app; enqueue
failure only logs — sweep compensates). e2e reset now also wipes the MinIO
photo-live/dev prefix; jest maps @photo/storage to TS source.

Spec review (live negative test) found s3-request-presigner unconditionally
unsigns content-type: header-less PUT returns 200, so the previous docblock
claiming signature enforcement was a false guarantee. Content-Type is now
documented as convention-only; head() returns contentType so the complete
step (Task 19) can verify it server-side against the session declaration.

Task 10: photos/photo_variants/upload_sessions/photo_jobs/outbox_events
on the CN schema (flat string FKs, no Prisma relations); migration
20260917120827_photo_upload_domain rewritten to utf8mb4_0900_bin per the

case for photo_jobs @@unique([photoId, type]) and the upload_sessions
